[U-Boot-Users] usb storage class CTL timeout problem

[Winston Lin]

Hi, 

Does anyone know why some USB mass storage devices work and some don't on the 
same board with the same u-boot 1.1.3?  I was able to track the msg down to 
hc_interrupt() used by submit_common_msg() in ./cpu/mpc5xxx/usb_ohci.c file.  
The hc_interrupt() always return 0xff (SF) and the submit_common_msg() in its 
for-loop times out on SF eventually.  

Regards,

Winston

I seem to remember a long time ago I had to increase the delays
in the OHCI driver to get it to work. It's been a long time
since I worked on it so I can't be more speicific then that...

I tried increasing the timeout var in the submit_common_msg() and that
did not work either.  Do you remember which delay it was or which
function (ie reset) this delay existed?

Thank you,

Winston

I think it was in ohci.c or whatever the driver file name is. I
remember turning on DEBUG caused it to start working. That's
what gave me the clue, when it started spitting out debug
messages and started working...

Because some are of poor quality and violate the USB specification?

BTW: did you try using a recent version of U-Boot?

 I have not... We have been using 1.1.3 as the code basis for our
current u-boot development and releases.  But I will be downloading the
1.1.4 and do a diff on the ohci driver for the mpc5200 processor.

Thank you,

 I just tried copying ohci driver, usb.c, cmd_usb.c, and usb_storage.c
files from 1.1.4 to my 1.1.3 source tree but same error msg occurred.
We have maybe 50-50 chance of running into the flash sticks that do not
work with our u-boot;  however, once we jump into linux, the same usb
device is properly recognized.  So, it's likely the linux usb driver is
more forgiving when it comes to usb devices that are not quite usb-spec
compliant?

May I ask why Freescale uses old  and  obsolete  code  as  basis  for
current   development   and  releases?  This  iseems  pretty  contra-
productive to me.

For example, I'm pretty frustrated that Freescale releases  old  code
for  the  MPC8349EMDS  board  which completely ignores, and partially
duplicates, all efforts or Kumar Gala and DENX for these boards.

This is a waste of effort, and bad service to your customers.

Please use top-of-tree.

Don't do this. Please use current code.

Hi Wolfgang,

I can't speak for all u-boot development effort within Freescale.  But
as for our small development team here, stability is more important.  If
we do see the need or have the time for moving on to the newer version,
we will proceed as we may need to in this case. 

Thank you,

Winston

[U-Boot-Users] usb storage class CTL timeout problem

[Privet]

I have the same problem with two different USB memory devices.
I am using U-boot 1.1.3 (I can not update it) on Freescale Media5200

One USB memory device is "Cruiser Micro USB Flash Drive". I do not know type
of another USB device. 
One device does not work at all. Another works very unstable. This message
may start appearing at any time. USB is virtually useless under U-boot in my
case.

Both of these USB memory devices works well with any other computers and
devices. Moreover any of them work well even with Media5200 when other
system is running. So I suspect that it is more probable that U-boot USB
driver has poor quality and probably violates USB specification. Isn't?
